Apple tree named ‘JHB 619 Cltv’

ABSTRACT

A new and distinct apple variety named ‘JHB 619 Cltv’ is provided. This variety is distinguished from other apple varieties by the unique color of its fruit.

Latin name of genus and species: Malus x domestica.

Variety denomination: ‘JHB 619 Cltv’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree named ‘JHB 619 Cltv’ that resulted from a limb mutation on a ‘Jonagold De Coster’ tree (U.S. Plant Pat. No. 8,049). The resulting tree was selected when growing in a cultivated area in an orchard managed by Adams County Nursery in Menhallen Township, Pennsylvania in a block named “Bull Valley.”

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a color photograph taken on Oct. 2, 2015, of a characteristic twig of a ‘JHB 619 Cltv’ tree at four years of age bearing typical leaves of the foliage.

FIG. 2 is a color photograph taken on Oct. 6, 2015, of characteristic mature fruit and a characteristic twig bearing typical leaves of the foliage of a ‘JHB 619 Cltv’ tree at four years of age. Whole fruit are presented in three positions and both a transverse and longitudinal cross section to illustrate their globose shape, flaring cavity and persistent sepals with erect tips.

FIG. 3 is a color photograph of a characteristic twig that illustrates the typical open flowers and flower buds of ‘JHB 619 Cltv’ observed on a tree at four and one-half years of age in a managed orchard in Aspers, Pennsylvania on Apr. 19, 2016.

FIG. 4 is a color photograph of a tree of ‘JHB 619 Cltv’, at time of harvest that illustrates the upright growth habit of a tree at four years of age in a managed orchard on Oct. 19, 2015.

FIG. 5 is a color photograph of the fruit color comparison of apples harvested on the same date. On left, apples of ‘JHB 619 Cltv’ harvested on Oct. 11, 2016, compared to, on right, a crate of ‘Jonagold De Coster’ apples harvested on the same date. The photograph shows that apples produced by ‘JHB 619 Cltv’ have distinctively more color than apples produced by ‘Jonagold De Coster’.

The colors of and illustration of this type may vary with lighting and other conditions under which conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED BOTANICAL DESCRIPTION

The ‘JHB 619 Cltv’ variety is distinguished from the related known cultivar ‘Jored’ (U.S. Plant Pat. No. 8,851 P): while both are strains of the unpatented ‘Jonagold’ variety, ‘JHB 619 Cltv’ produces fruit with distinctly different overcolor and lenticels color values and no observed chimaera stripes, as discussed more fully below. ‘JHB 619 Cltv’ also differs from parent ‘Jonagold De Coster’ in producing fruit that have an average of 55-65% more red overcolor as a blush over the surface, distinctly different ground coloring and stem pit coloring, and more prominent lenticels, as discussed more fully below.

The variety was asexually reproduced in a commercial orchard block in Aspers, PA. Asexual reproduction of this new variety by topworking onto M9(337) rootstock (non-patented) shows that the claimed cultivar is stable and reproduces true to type in successive generations of asexual reproduction.

The following detailed description of the ‘JHB 619 Cltv’ variety is based on observations of asexually reproduced trees of 4 years of age growing on M9(337) rootstock (non-patented), and measurements taken on Jun. 30, 2023, in a managed orchard in Adams County, Aspers, PA.

Color designations are made with reference to The Royal Horticultural Society (R.H.S.) Colour Chart (1966 Ed.). However, colors are approximate as color depends on horticultural practices, such as light level, fertilization rate, and other conditions. Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (such as, light, temperature, moisture, nutrient availability) or other factors. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise.
